This application is` of thetype of chair shown in my co-pending e onl line application 209,053filed July 28, 1927.# ,1150" In Fig. 1 `of the drawings I have shown:two chairs 'in their adjusted positions, with the back cushions placedbetweenl them ready to form a berth or bed; Each chair is'fpro. videdwith a base 1 mounted upon a pedesf tal 2. A shaft connects theb'aseandthe pedestal and projects into each one so as to'- form a strongconnection which permits rotation of the chair on the pedestal. i Thebase.

1V is provided with a base pla-te 4, SomeV means isv provided Vforlocking the base inV any desired'position withV relation to thepedestal. As herein shown, the pedestal is Y provided with a seriesofopenings 5 to `re-v ceive the end.. of a' pin 6.- VThis 'pin is providedwith a'l shoulder'` 7 which limits' its .j movement toward the pedestal.A sliri'ngr 581, inclosed in a cylinderv 9;.nor1jnally presses the pintoward the pedestal so as to normalf. e

means is providedfor moving thepin't'o disaA 1 connect the base and thepedestal. As herel' in show'n,` the pin is providectwitha 'pro j ection10. A rod 11 is mounted' in 4guides 12 connectedrwith the base plate 4andis a`rf ranged to be moved longitudinally insaid l guides; This rodis provided with a'handle" V13 and an inclined engaging facel14;.whicl'i f engages the projection V10 when the rodis" j movedlongitudinally in one direction. This lifts the p in 6 so as todisconnect it4 from the pedestal. The chair may thenbe rotated-so? as tomove it to the desired position.; The rod 11l is then moved in theopposite direc-4 tion and the spring forces the pin into onev 4oftheopenings inthe pedestal.l

Some means is provided for adjusting the chair so as to increase itswidth andi for alsof` increasing the wijdth'of the vhack?. The chairk isprovided withtwo side piecesV 15 andal;

larged sectional viiewrtaken]- 5v5- i which with the cushions 17 and 18act as the arms of the chair. *Y The side piece is connected with thebottom 19 (see Figs. 4, 5, and 15). The arm side piece 16 is connectedwith'the sliding bottom plate 20. The plate 4 and .bottom ,9have stopswhichlimit the lateral vmotion. The back of the chair is formed'ofsections 21 and 22. The Vback sec'- tion 21 is connected with thesliding bottom plate and the back section 22 is connected Y with vthebottom 19.v "lhesliding bottom plate 20 slides laterallyfwith regard'tothe bottom 1 9 and is held from upward move# f j rment by the guide23attached to thebottom.

Some means is provided for locking thebottom baise plateand slidingplate togetherwhen thechair is in itsVnormal po.-y .sit1on,' and for unlocking them and permitting them.V tobe moved pto widen the chair andv tofbe moved backward or forward along'.plate 2O. are locked together by the Ypin 24,

which connected withI the` base plate -4 and -which passes throughopeningsin s aidparts the''base plate. In the construction shown, theseparts are 'locked by means of :movable pins. The ,bottom 19 andslidingbottom as shown in`Fig. 19. ',The pin-U24 passes through theyhole 25`vvhen the parts are in; their normal position, and, through thelhole V2,6 when the bottom. is moved jto the rear.

The bottom and bottom sliding plate are moved to the rear alongl thebase plate 4 by thepin 27, which. worksin Ya diagonal slot 28 in thesliding bottom Vplate (see Fig. 8).

This pin also worksin slot 19a ofbottom 740; controlled by. thesamefcontrolling device..

' As herein shown, pin A241is provided,withvv av i mentfAspringv31,4located in a'hmising"V 32 (see Figs,y 9 and 19),.no`rmally holdsthepin in itsrlockingposition. The pin is provided with vane'ngagingpart 3 3 which is engaged f by-'ain armj-341on a rock shaft, 35. Thep-inVl27fisprovidedV with' a shoulder36 which lim`v 19. Thisdiagonal slothaspa straight p oraA tion 29 at the end. The pins 24 and 2 7 areShoulder' 30 which Vlimits its .upward ,moveits 'itsupward movement andisheld in its lookingjpositionby a spring 37 located vin a Y housing38(see Fig. 6). The pin 27 is pro'- 'v'.idedwith an engaging part V39which is enf gaged by an' arm 40-on;theshaft 35, this be-l ing-thesame-shaft to which the arrn34 is attjached.` Theshaft -is` connected byvan arm 41 V,Withfa shaft 42, whichis rotatably mounted'in suitablebearings attached to the l vbase plate 4 (see Fig. 9).

' TheJ Shaft 421s provided Win15 .hdndldda Y providedwith means formoving it longitudi- Ynally. As herein shown, itis provided-:with

by vmeans of ywhich itis rocked. This shaft is ythe Y-projections44 and45,-"which engage a Acam-,46. When the'handle 43 is vmoved to V'oneside,the shaft 42 is moved longitudinally in one direction sofas to rock theshaft 35 and move the arm 34 to release the pinr24. When said handle ismoved to theother side, the

lshaft ismoved longitudinallyin the other direction and rocks the shaft35 4so as to move varmand unlock pin .27.' It will thus be seen thatAthe twoipins arecontrolled by the rsame mechanism. `v l The back section21'slides along guides 20a and 205 onA section22, Fig. 6, and isYprovided with a sliding partj 47. This sliding part-is provided withapin 48 which works in a slot 1 49 in the 'back section 21 andslidesalong guides47 and`47bV connected with section 21.

This armcushion is lifted so as to lift thepin out of the slot and is then placed between the seat cushion 57 andthe side piece 16, as shown in Fig. 5, the other parts being as showninsaid iigure. The back cushions are then removed and placed in positionbetween the two chairs, as shown in F'igs. 1 and 2. rl."he devicefis nowready'to receive the proper bedding to make a berth or'bed. When theVchairs are used in sleeping carsvand are made` up into berths, the usualpartitions 74 are placed between the berths, as shown in Fig. 5. Thesepartitions have connected therewith ythe sliding part 75, which may beslid down to Acover. the spacel above .the arm cushion 17 .Y The piece7.) i held in position by a pin 76 connected with the partition bychains 77.

It will thus be seen that Ihave here a chair construction wherein thechairs may be used as ordinary chairs.

time asa chair car and at night as a sleeping y car. W here'the carmakes a dayrun betweencities, the car can be used going in and can bereturned at night as asleeping car,

- thus .keeping the cary continuously in use and reducing thenumber ofcars necessary where the ordinary chair car `and sleeping car are used.A Y c vy Rail l on the car is preferably-provided f with lugs 55a toelevate the back cushion the proper height (see Figs. 2 and V3). Thelugs 57a, on cushion 57 which work in notches 57 b in sliding bottom 20,cause Vthe cushion to be moved back to closing' position when the Ybottom parts are moved to this position.

They also relieve the strain on pin 58. .The seatV can be widened whenpin 27 is withdrawn from Vdiagonal slot 28 `so that the chairs can beused as single chairs or double chairs. rlhe seat can be both widenedand deepened for a bed by withdrawing pin 24 from hole 25. The baseplate 4 is provided with guides 4 awhich tit in between the bottom 19and the angles 4b connected with saidbottom so that the bottom 19 andassociated parts It will further be seen that suoli chairs can bewidened so as to form Y double chairs-that is, a chair for two people.

lcVhen these chairs are used on cars,

can be slid back upon the base plate f4 when the pin 24 is withdrawnfrom the hole `28 in the sliding'bottom plate20. Durin l.this
